To all 107mm 'it may concern.'

lle it known that I, lVlLLniM A. PATN'I'ER, of' Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Chemical Fire-Extinguishere, of which the followingis a specification.

An objectot' my inventionis to provide a new and improved chemical fire extinguisher ot simple and etlicient construction, particuhu'ly designed to meet the requirements to which apparatus or' this; class are subjected.

A further object of my invention is to provide a new and improved separable cage or bottle holder adapted to permit the insertion and removal of the acid containing bottle or receptacle through a side oit' the cage.

In the accompanying drawing, which Figure l is a central vertical sectional view of a lire extinguisher embodying,r my invention, the section beingr taken on line I--`I o't' Fig. 3; Fig. 2, a `vertical sectional view similar to Fig. l showingthe extinguisher inverted; Fig. 3, a plan with the cap omitted; Fig. 4, an enlarged vertical sectional view and Fig. 5, a perspective view oil" the cage or i bottle holder.

Referring` to the drawing, l designates a casing or tank of the portable ire extinguisher,l preferably made ol metal. The tank is provided with a metallic neck 2 secured to the upper portion ot' the tank in any suitable manner; said neck, illnstrated, beingf formed with externally disposed threads B'and inwardly projecting lugs 4;.

5 designates the usual screw cap or cover` adapted to be placed on the neck .2 and have its threaded portions 6 in engagement with the threads of the metallic neck.

7 designates a gasket interposed between the cap and the upper end ot' the neck.

Characteristic and importanti features ot the present. invention coxrun'i.-iA the bottle holder or cage per .vc and the;l eombimition and arrangement of parts (constituting my heads QL of Slightly greater improved .tire extinguisher.

The cage or bottle holder. ae illustrated constitutes a seat for the acid containing` bottle l5.

1G designates side rode or members having their ends entered in the respective openings 9 and 12; these rods are secured to lho `top and bottom members and rigidly connect said members.

Coiipcratinp; with the parts just dcaoribcd, l provide a cage closure or bottle retaining device 17 cinnprisingr, in the form illustrated, a central yokiA portion 1.8 preferably made oi two parts with the outer ende lt) of said parts embracing' the side rods ot the cage. The device 17 is provided with two upwardly project-ineY rods 520, said rods Q0 are entered in and adapted for vertical movement in the apertured lugs l0 of the top member. Rode 20 are provided with diameter than the openings ot lugs l() and support the closure device in the desired operative 'position when. the parts are aseemiilcd.

22 designates a gravity stopper for the bottle l5, and, v sinned to rest upon the upper end of the neck o said bottle 15 when the apparatus is; in an upright position; when the apparatus is inverted as shown by Fig. 2, the stopper falls againstv a seat 23 of the cap To remove the acid containing bottle 15 for the purpose of replacing the same or refilling the bottle, the cap 5 is removed from the extinguisher, thus permitting the separable cage together with the bottle to be littcdtree oil the apparatus and placed in a vertical position. 'l'he constructicin of the cage is such that it will stand alone and can be maintained in an upright position during the act of removing;i or inserting a bottle. While in this poeitiou, the bottle l5 may be readily removed from the cage by raising the bottle retaining or closure as shown by Fig. l, is ded' 'and a vertically movabl l top member vprovided 15,. l connecting the top having supporting means, l neck, of

K holder supported by the neck independently seated upon the neck, a bottom mem -necting the top and a vertically movable cage .ing means `for limiting Ament and cooperating withthe side mem er,

i device' 17 verticall upon the side rods into the position as in icated by Fig. 5, and the bottle me thenberemoved. I

What claim is l. -ire extinguisher ca'ge comprising a ton member provided with an apertnred portion, a bottom member, a side member connecting the topanti bottom members,
